Free frozen yogurt: In the summertime, people love frozen treats -- especially when they're free. From now through July 20, the Ben & Jerry's scoop truck is touring Portland, stopping at local businesses, non-profits and community events to dish up samples of its new Greek Frozen Yogurt. With a little social media savvy-ness and a worthwhile cause, you could have Ben & Jerry's come straight to you to serve up free scoops of four different flavors. Just Tweet the truck, @BenJerrysWest, and tell them about your group or cause.
